internet explorer control click

Hi everybody,

I found an example code on the internet on how you can take over control of an already opened internet explorer application.
It all works perfect exept that I can't identify my element on a website cause it's a javascript.

this is the element where I need to send a click to.

HTML Code: 

as you can see there is no tag or name in it. So I don't know on what, or how I can run this element.

The code above is what I need to run, but I don't know what to put in place of the "myButton".

Any ideas??
